This patch is composed of two new files : - mpp.c which is mainly inspired by the same file as in mach-kirkwood - mpp.h that is written from the documentation provided by Marvell http://www.marvell.com/products/processors/embedded/discovery_innovation/HW_MV78100_OpenSource.pdf Moreover, due to some implementation problem, I have defined some MPPX_UNUSED that offer developers the possibility to SET MPP to some unused value (such as for Buffalo WXL). Note: This patch doesn't support MV78200 yet (only 78100 MPP lines have been written) Signed-off-by: Sebastien Requiem <sebastien@kolios.dk> Signed-off-by: Nicolas Pitre <nico@marvell.com>
